Comment Depends if you want to support it (Score 2) 23

That really is the big issue with a self build: If something goes wrong, you have to track it down and handle all the support. If you get a pre-built from a good vendor, they'll handle it all. Say what you want about Dell, but all you have to do is run their diags (baked in to the UEFI) and call them with the code, they'll send a dude with the parts needed.

So that should be the major thing you think about. If you don't want to do support, then buy it from a vendor that will provide you with support to the level you require. I tend to recommend Dell because their hardware is reasonable and they have support available everywhere. They subcontract it, but it all works well. We use it at work all the time.

If you are willing to do support yourself, then building it gets you precisely what you want. I build my system at home because I have very exacting requirements for what I'm after and nobody has that kind of thing for sale. Like I don't want a "good large power supply", I want a Seasonic Platinum 1000, nothing else.

Also you'll find that generally at the higher end of things you save money building a system. For more consumer/office range stuff it usually is a wash: They build the mass market systems around as cheap as you could afford to. However when you start talking higher end gaming stuff, you can pay a large premium for things.

As an example I just built a system for a good friend of mine. He wanted some very, very high end hardware and pretty specific requirements. Origin PC would get him what he wanted... for about $9,000. I put it together for around $6,000. The gamer stuff often commands a hefty premium.

In London, bicycles effectively use about 2MPG of diesel by slowing large numbers of buses and trucks to the position where they are unable to get out of low gear. They are one of the biggest causes of pollution from diesel.

If you got the damn bikes of the road, the diesel vehicles would pollute far less.

And, as for public transport - sure, take your desktop computer, server or laser printer (or even your weekly supermarket shopping) under your arm on London transport in the rush hour. You can post the video on Youtube afterwards.

Comment Tidal (Score 1) 155

Tidal power is the way to go - I presume most people would not include it in hydro - because hydro generally involves piling a lot of water on land where it floods out peasants and causes earthquakes, whereas putting a nodding duck off the west coast of Scotland would have little impact on the environment, a propeller in the current off the south coast of Trinidad would have little impact on fish.

And the sea is a convenient place to dump the waste heat too.

And yet for all your misdirected Windows whining DirectX for Windows is the only area that AMD cards perform well. Their Linux drivers blow, as noted by other posts here, and that is because AMD can't write OpenGL drivers to save their life.

nVidia, on the other hand, has extremely fast and solid drivers for Linux.

Comment Well of course, because Linux is OpenGL (Score 1) 50

And AMD can't handle OpenGL. I don't know why, I'm not sure what's so hard, I'm not sure if there's a monster that guards the OpenGL specs in the AMD office or something, but they have sucked at GL for over a decade, and show no signs of getting any better. They can't claim it is because of an API limitation either. For whatever you want to say about the mess that is OpenGL, nVidia makes their GL drivers dead even with their DX drivers. You can use either rendering path and can't tell the difference in features or speed.

That is also why I'm real skeptical that Vulkan is going to do anything for AMD. While they are heavily involved in the development, they are involved with OpenGL's development too (ATi was a voting member on the ARB and is a promoter with Khronos Group). Given that Vulkan is heavily GL based, originally being named glNext, I worry that AMD will suck at performance with it as well.

Not the driver, that's out, but that they are going to change how they do drivers. They've said that numerous times before, and always the situation is the same. They are very slow at getting actual release drivers out (they are forever beta versions) and their OpenGL performance and support is garbage (to the point that HFSS would fail to run on systems with AMD cards).

So AMD: Less talk, more good drivers. I want to support you, I really do, but I've been burned too many times.

Comment And what does that cost for gigabit routing? (Score 1) 111

The problem PFSense has as compared to consumer routers is that running on normal Intel CPUs it needs more CPU power (and thus cost) to be able to forward a given amount of traffic. Plus all the NICs and such are separate silicon. Boradcom makes little all-in-one chips that have a couple of ARM cores that have acceleration for routing and so on. Also they have things like an ethernet switch and ethernet PHYs on the chip so they needn't be added. Have a look at a BCM4709A for an example that is popular in routers.

PFSense is good but it is not the most economical thing if you are talking features matching a consumer router, meaning gig routing, multiple ports, and wifi, you can have your costs go up a fair bit. Particularly if you also then want it to be fairly small and low power. If you hop over to PFSense's site it would cost about $575 for a SG-2440 with WiFi which would give features roughly on par with a consumer router.

While I'd much rather have that over a consumer router, a consumer router is in fact what I have because I didn't want to spend a ton of money for a home router.

Comment This is the only answer that matters (Score 5, Informative) 373

If this is for the kids, then they need to make the choice. Mostly because online play tends to only work in console. So if all their friends have an Xbox one and they have a PS4, then they can't play games together.

If you want any kind of technical considerations or the like the PS4 is faster than the Xbone because of details with hardware design so it will end up rendering things at a higher resolution and so on. Also the controllers feel very different in the hands, and some people have a strong preference. I like the Xbone controllers much better and they are what I use with my PC (I have a PS4 controller as well).

Really though what matters is choosing the one that has the games you want, and that plays with the people you want to play with. The rest is secondary.

To be fair, they have attempted to pretend they thwarted other attacks.

They also claim the data is used to attack organised clime. There is no evidence of success there either.

In fact, there is considerable evidence that they have no idea how to use the data in any meaningful way. Perhaps they should hire the people targetting online adverts to manage the data. Oh, wait ...
